1. Fragment caching

• use belongs_to :parent, touch: true to invalidate parent objects when child is modified
• share cache between pages
  • use CSS to modify fragment look
  • use JS to modify fragment based e.g. on current user - e.g. hide "edit" button if he doesn't have enough privileges or hide his name from list of project contacts
• use <html-version>/<cache-key> as fragment cache key, where <html-version> is incremented manually after every change in HTML/CSS of the fragment and <cache-key> is [class]/[id]-[timestamp] e.g. "projects/15-20110218104500"

2. Caching user's home page (same URL for all visitors, but different content)

• can't cache response in gateway proxy

1. Isolated engine - short description
2. Create an engine: rails plugin new <name> --full --mounted - undocumented
3. mv <name> vendor/apps
4. cleanup engine's Gemfile (?)
5. add engine to main app's Gemfile
6. routes in engine's config/routes.rb then mount in main app's config/routes.rb
7. views - lookup paths; default paths, might need to reverse order
8. tests - dummy app; use the main app instead
9. namespaced controllers and views
